OpenWrt support for Tenda TX9 PRO AX3000

So I bought this router Tenda TX9 PRO AX3000
TX9 Pro web page
and I've been using it for 2 years. It does not run that well and was crashing 2 to 3 times per week and was not logging any problems but from hardware point of view it has pretty nice specs for a lower price so I was wondering if I coud install openWrt and be done with it.

So I went to Table of Hardware and did not found this device.
After that I thought it might not be that hard to add support for my device and I found this
New device support

And first step on the list was:

Make a detailed list of chips on the device and find info about support for them. Focus on processor, flash, ethernet and wireless

Right so the device was for some reason overheating so I was not against openning it and looking inside for chips and then adding a better cooling.

And look at that it has only metal plate for cooling, but what can you expect from a budget router. From this point I didn't see a serial port but it should have one.

Under the switch ports should be some relays?
Brand JWD
DG36002 G
tried to google it and found nothing.

Closer look on it.

view from the bottom

After taking off the metal plates

I can see the serial port

The chips are encased inside a metalic frame kind of standard practice.
There are only three chips outside it.
The one above
Found only this one without the sq at the end, but should be some sub type of this product.
IF this chip is the same it should have 16MB flash memory.

Now for those two small chips under the metal casing
On the left

On the right


Again tried to google it but found almost nothing. Under them there are connections for 2.4G a 5G antenna so I guess something to do with Wifi.

Now for the chips under the metalic casing.

Again another
2048 CN


I guess four antenas four wifi chips.

Now this chip had the most cooling so I guess should be the the most important.


For the first found nothing and for the SLN23
SLN23 mouser
Network Controller & Processor ICs

And the other cover


the only thing I found under SLMQ3
GRX350A3BC160 - Network Processors

And the last chip

P09H801S 047
This is the first I had exact match
That is ram.

Now I have to buy thermal pads and find some cooler that I can use on the top side.
Maybe this will help someone to find the other parts I was not able to identify.
I would like some advice where to go from here.
I will try and see what ways there are to get in to the bootloader of this router but never done this before. Any help would be appreciated.

PS: The guy that made the rule novice users can only have one media file in a post clearly hates photo documentation :smile:

That looks like a lantiq / Maxlinear SOC - none of which are supported.

Earlier versions of these were supported, but they're bascially abandoned now.
This is the closest I can find of someone getting it working - however there are no wifi modules available so it is a dead end.
